SELF-REGULATED CURRENT-CONDUCTING SEALING MATERIAL Russian patent published in 2010 - IPC H01B1/22 

FIELD: electricity.

SUBSTANCE: invention relates to the field of electrical engineering, in particular to self-regulated current-conducting sealing material arranged on the basis of polysulfide oligomers (Thiokol) and may find application in development of flexible electric heating elements, and also sealants. In proposed self-regulated compound, electric resistance of material increases as electric current flows through it, due to the fact that in warmer sections material of compound expands, thus reducing a number of current-conducting "tracks" made of carbon material. Current-conducting sealing compound comprises the following components, wt parts: Thiokol NVB-2 - 100, technical carbon P-803 - 30-40, manganese dioxide in the form of paste No.9 - 15-35, diphenyl guanidine - 1, as self-regulated current conducting material.

EFFECT: efficient "self-regulation" of specific electric resistance in the range of temperatures from -30°C to +40°C .
